/**
 * Implements the driver for the facade design pattern example. 
 *
 * Intent: Provide a unified interface to a set of interfaces in a 
 * subsystem. Facade defines a higher-level interface that makes the 
 * subsystem easier to use.
 *
 * The subsystem consists of three classes that provide low-level
 * string manipulation and output functionality: <code>RegularScreen</code>,
 * <code>Decoration</code>, and <code>StringTransformer</code>. The Facade
 * class <code>OutputFacade</code> procides a higher-level interface
 * to output strings. This class calls methods on that higer-level interface.
 *
 * This is the Java version.
